Flow Meter Calibration

Accredited Flow Calibration Laboratory–ISO /CNAS

Darhor Tech established the calibration Laboratory since 2001 which now is one of the few flow calibration laboratories in China.

Our laboratory was equipped with 4 sets of flow standard devices with total 8 pipelines. Our variable head dynamic volumetric standard devices can calibrated maximal flowrate up to 20000m3/h, and the total uncertainty of the system is superior to 0.037%.

We also imported Krohne calibration devices with high potential tank steady head static weighing method and 4 calibrating pipelines that is capable for calibration of fluid flow meter with size of DN3 ~ DN1200.

Darhor Tech calibration laboratory has established quality manual and procedure documentation in compliance with 《Laboratory
Accreditation Standard》 stipulated by CNAS (CNAS--China National Accreditation Service for Conformity Assessment, and obtained the approval of CNAS to be authorized by Zhejiang Province Institute of Metrology.
